Questions tagged [chaos]

Anything related to chaotic systems or chaos theory. Chaotic systems are systems that are extremely sensitive to initial conditions (e.g. round-off error in data stored digitally) thus leading to the impossibility of predicting their long-term evolution. The tag is mostly relevant to cases where algorithms show chaotic behavior.

Why does this C++ function produce chaotic output?

I have the following code: int main ( int argc, char **argv ){ double lambda = 4; double x = .2; for ( int i=1; i<=30; i++ ) { printf( "%.5f \n", x ); x = lambda * x * (1-x); } } That outputs the following: 0.20000 0.64000…

Integrating chaotic systems

I have 3 equations as follows u'= -a*(u-v) v'= c*u-v-u*w w'= -b*w+u*v a=5.0 b=0.9 and c=8.2 Im trying to use scipy.integrate.odeint solve from t=0 to t=10 My initial conditions are u(0)=0, v(0)=1.0 and w(0)=2.0 I can't many useful notes on…

Initial weights causing stagnation in XOR function learning-neural network

I have a neural network with 2 entry variables, 1 hidden layer with 2 neurons and the output layer with one output neuron. When I start with some randomly (from 0 to 1) generated weights, the network learns the XOR function very fast and good, but…

Normalizing data and applying colormap results in rotated image using matplotlib?

So I wanted to see if I could make fractal flames using matplotlib and figured a good test would be the sierpinski triangle. I modified a working version I had that simply performed the chaos game by normalizing the x range from -2, 2 to 0, 400 and…

Controlling accuracy while iterating chaotic maps in Matlab

I'd like to be able to control the decimal accuracy exactly while iterating a chaotic map. In particular, I'd like to make sure that Matlab uses no more / no less than the value p I specify in the following function: function out =…

In "the code", Marcus du Sautoy, tries to explain Chaos Theory

So at a certain point, he starts with this silly equation He starts talking about lemmings and how the rate of growth fluctuates and can lead to very unpredictable chaos Pnext = R * P - R * P * P simplified to Pnext = R * P(1-P) Wich is the…

How can I transfer the data that my program generates to a new turtle program to use?

Seen below is the code for my iteration program. I want to be able to use turtle graphics to take each parameter (k) and have the equations output plotted against its corresponding k value. This should create a feigenbaum diagram if im not mistaken?…
